Wheel Accessories

Whether its simple stylish dust caps and valve stem covers or replacement wheel bolts or nuts, anything wheel related can be found here. Rockshore Automotive also has locking wheel nuts and bolts for most UK vehicle applications and lightweight or flush fit valves by Richbrook. If your wheels are in need of some tlc then we have a very handy Alloy Wheel Repair kit to bring them back to life and wheel arch guard if the arches are looking a little worse for wear. If you're looking for a tyre pressure monitoring system, then you can find them here also, along with all the spares for the Tyresure systems.

The Tyresure tyre pressure monitoring system is fairly straightforward to install. Installation of the display unit can be carried out easily by the car owner as it simply fixes to a suitable place in the front of the vehicle, for example the dashboard. It is powered by a lead to the cigarette lighter which is included (car option only) or can be modified to be hardwired to the vehicle’s 12v system if preferred.

Installation of the sensors and aluminium valves will need to be carried out by a tyre fitting technician at a local tyre fitting centre or garage (the costs should be minimal and be similar to having a wheel balance and new rubber valve fitted).The tyre fitter will simply fit the sensors to the aluminium valves (included) which are then fitted inside the wheel (sensor is hidden). The aluminium valve is then bolted in as normal (aluminium valves simply replace existing standard black rubber or metal valves). Once the tyres have been re-inflated and re-fitted to the vehicle, the display unit will automatically calibrate to the sensors. The sensors will then wirelessly connect to the display unit indicating audibly and visually the tyre pressures, tyre temperature and each tyre/wheel position on the vehicle.

What are the correct tyre pressures for my car?

Tyre pressures for your particular vehicle will be specified in the vehicle's handbook and they may also be shown on a sticker on the inside of the driver's door. The tyre pressures quoted will be for cold tyres only. Normally two numbers will be quoted; one for normal everyday use and a higher figure for when the vehicle carries load. You must therefore ensure that the tyre pressures are adjusted accordingly. If you have lost your handbook or are unable to find out the correct tyre pressures for your vehicle, you should refer to your vehicle manufacturer.

Important reasons why you should have the correct tyre pressure:
Safety – under inflation or over inflation will affect the grip and control and increase braking distances Life of the tyre – under or over inflation increases wear Fuel economy – under inflation increases fuel consumption

You should only check tyre pressures when the tyres are cold so if they have been driven on, you should wait at least one hour before checking the pressures. You should also check your tyre pressures regularly and at least every two weeks.

When checking tyre pressures, its always a good time to have a look at the tyres to make sure they aren't damaged and that no bulges or deep cuts are apparent. A bulge in a tyre indicates internal structure damage and the tyre must be replaced immediately. Similarly if a deep cut is found and enough to show the internal structure of the tyre, then this also means that the tyre should be replaced.

The common methods of checking tyre pressures is of course to use a good tyre pressure gauge but did you know that you can monitor both tyre pressures and temperatures constantly by using a tyre pressure monitoring system. Its very easy to install and will alert you when either pressures or temperatures are abnormal giving you piece of mind.

How do I find out what size my tyres and wheels are?

To find out what size tyres your vehicle has you just need to look at the tyres. On the sidewall of each tyre there will be a sequence of numbers for example, 195/65/R15 H. In this example, the 195 is the width of the tyre in millimetres; the 65 is the profile (65% of the width) and the number 15 is the diameter width of your wheel in inches. The letter R stands for Radial and the last letter (in this example H) is the speed rating of the particular tyre.

To find out what size diameter wheels you have on your car you need to look at the tyres. On the sidewall of your tyres there will be a sequence of numbers, for example 195/65/R15. The last two digits is the diameter size of your wheels so, in this example, the size of the wheels is 15 inch.
